Teasing out the microbiome of the Kansas prairie
PNNL scientists have untangled a soil metagenome -- all the genetic material recovered from a sample of soil -- more fully than ever before, reconstructing portions of the genomes of 129 species of microbes. While it's only a tiny proportion of the estimated 100,000 species in the sample, it's a leap forward for scientists who have had only a fraction of that success to date.

Researchers find molecular switch that triggers bacterial pathogenicity
A new study led by scientists at Berkeley Lab has revealed that the supercoiling of bacterial chromosomes around histone-like proteins can trigger the expression of genes that make the microbe invasive. The discovery could provide a new target for the development of drugs to prevent or treat bacterial infection.

When the going gets tough, the tough get growing
While relentless bright light brings many forms of cyanobacteria to their knees -- figuratively, of course -- Synechococcus sp. PCC 7002 does the opposite, thriving and growing at a rate that far outpaces most of its peers. Now researchers know why: it triples in size to accommodate a rapid expansion of the cellular machinery it uses to build proteins.

Scientists create new thin material that mimics cell membranes
Materials scientists have created a new material that performs like a cell membrane found in nature. Such a material has long been sought for applications as varied as water purification and drug delivery. The material can assemble itself into a sheet thinner but stabler than a soap bubble, the researchers report July 12 in Nature Communications.

Comparing fungal secretions to uncover carbon compound degradation pathways
Fungal secretomes, those collections of all molecules secreted by a cell, contain enzymes that can break down plant cell wall components, useful to bioenergy researchers looking to cost-effectively convert plant mass into sustainable, alternative transportation fuels. In a study published July 19, 2016, in PLOS ONE, a comparative analysis of four fungal secretomes revealed more about the variety of pathways they deploy to break down carbon compounds.

Scientists determine structure of enzyme linked with key cell-signaling protein
Scientists have captured atomic level snapshots showing how one key enzyme modifies a protein involved in turning genes on or off inside cells. Understanding this process helps explain how complex organisms can arise from a finite number of genes. The research also identifies links between defects in this particular enzyme and certain cancers, potentially pointing to new drug targets.

Ovarian cancer study provides painstaking look at inner workings of tumors
Scientists have examined the collections of proteins in the tumors of 169 ovarian cancer patients to identify critical proteins present in their tumors. The researchers say their achievement illustrates the power of combining genomic and proteomic data -- an approach known as proteogenomics -- to yield a more complete picture of the biology of a cancer that is the fifth leading cause of cancer deaths among women in the United States.

See and sort: Developing novel techniques to visualize uncultured microbial cell activity
In a study published online the week of June 27, 2016 in the Proceedings of the National Academy of Sciences (PNAS), Caltech and DOE Joint Genome Institute researchers utilized a recently refined technique to identify both individual active cells, and single clusters of active bacteria and archaea within microbial communities. The DOE is interested in learning how the planet's 'microbial dark matter' can be harnessed for energy and environmental challenges.

Sandia researchers discover mechanism for Rift Valley fever virus infection
Viruses can't live without us -- literally. As obligate parasites, viruses need a host cell to survive. Scientists are exploiting this characteristic by developing therapeutics that close off pathways necessary for viral infection, essentially stopping pathogens in their tracks. Rift Valley fever virus and other bunyaviruses may soon be added to the list of viruses denied access to a human host. Sandia National Laboratories researchers have discovered a mechanism by which RVFV hijacks the host machinery to cause infection.

On the path toward bionic enzymes
Berkeley Lab chemists have successfully married chemistry and biology to create reactions never before possible. They did this by replacing the iron normally found in the muscle protein myoglobin with iridium, a noble metal not known to be used by living systems.

Better combustion for power generation
As US utility companies replace coal-fired power plants with natural gas, a collaboration between GE and Oak Ridge National Laboratory is contributing to efficiency gains in GE's H-class gas turbines. GE researchers produced the first simulation involving multiple gas turbine combustors to study combustion interactions that are impractical to test physically. Advanced simulation is projected to results in a full percentage-point gain in turbine efficiency.
